Alzheimer disease - a progressive neurological disorder which kills the brain cells and hinders social and occupational functions - can be avoided by the use of contraceptive pills, suggests a new research.

CONTRACEPTIVE PILLS that are used by many middle-aged women help to improve their brain power, and their effect lasts for many years. This new discovery could help in preventing the declining cognitive function, which is a condition associated with Alzheimer's disease.

The research was done on 262 women with an average age of 52. They were tested on the cognitive function. The usage of contraceptive pills by the women was noted. And the result concluded that the women using contraceptive pills are showing better performance in certain brain related functions when compared to those who never used contraceptive pills.

Alzheimer disease is a tricky disease and cannot be diagnosed easily, because every patient has a unique sign or symptom for the disease. The disease is usually divided into several stages namely Pre-Dementia Stage, Mild Alzheimer's Stage, Moderate Alzheimer's Stage, and Severe Alzheimer's Stage.

A great deal of research is being done on this disease and this new research on contraceptive pills is a milestone. The several factors associated with developing the disease are age, family history, Down's Syndrome, whiplash and head injuries, mild cognitive impairment, gender, heart related problems and some other disease conditions.

Experts say that the key hormone - estrogen present in the contraceptive pills is responsible for hardening the arteries, which in turn increases the blood supply to the brain helping to function it properly and it also encourages the growth of certain cells in the brain. Lead researcher Kelly Egan told Mail Online, “Our analysis indicated that hormonal contraceptive use may have a protective cognitive effect, even years after use is discontinued. This is especially true in subjects with a longer duration of use.”
